I think gathering the data is possible
I do, too, but only in a very sloppy way.
to have a meaningful analysis you'd have to compare the same player with the same skills at different levels of Experience, wouldn't you? That's kind of a very difficult task to accomplish and if you do it with only 1 or 2 levels or experience it's unlikely to be noticeable.
Do you disagree with yourself? Haha!
I agree more with your second point of view. In order to do a meaningful analysis, you'd have to have the same players against the same players and the only thing that changes is their experience. Good luck sorting that out!!

I guess we just have to live with conjecture (and what it states in the game manual) for now.
